A greater number of guns were employed than in any operation up to that time; although in number, and still more in calibre, the artillery then used have in, modern times, been thrown into the shade by the sieges of Sebastopol and Paris. Gibraltar differs, however, from these sieges, inasmuch as the defence was a successful one and, indeed, at no period of the investment was the fortress in any danger of capture, save by hunger. At that period England was not, as she afterwards became, invincible by sea; and as we were engaged at the same time in war with France, Spain, Holland, and the United States, it was only occasionally that a fleet could be spared to bring succour and provisions to the beleaguered garrison. Scurvy was the direst enemy of the defenders. The art of preserving meat in tins had not been discovered, and they were forced to subsist almost entirely upon salt meat. During the first year of the siege the supply of fresh vegetables was scanty, in the extreme, and the garrison consequently suffered so severely, from scurvy, that at one time scarcely half of the men of the garrison were strong enough to carry a firelock, and perform their duty. The providential capture of a vessel laden with oranges and lemons checked the ravages of the scourge; and the successful efforts of the garrison to raise vegetables prevented it from ever, afterwards, getting a firm hold upon them.
